OIL-CAN.

qpoelflcation of Letters Intent.

Patented Sept. 16, L913.

mlslcaflnu filed November 9,1812. Serial No.-730,898.

To all whom-may conaem Be it known that I, ALmr T. Boom, a citizen of the United :States, and resident of Waterbury, county of New Haven, State- 0f Connecticut, have invented an Improvement in Gil-Cans, of which the following description, in connection with the accompimying drawings, is a specification, like characters Ithe drawing representing like Hts. his invention relates to sheet-metal oilcans and more particularly to the connection :between theout and the can body, and it has for :its :Eject the production :of :1 novel and eflicient oil-tight and readily separable 'coimection which can be manufactured readily :and at :a low ccst, t-he co1mectinnbeing so constructed and anranged that the spout and the body :of the, can may be quickly discoimected ('71"C01)J18Ctd.

As will appear Zhereinazlitcr :the top of the can body has formed upon it, integrally therewith, :one member of the connection, the other member oe" the connection being secured rigidly to the spout without .the use eaf :solder and in :an ell-tight manner.

The various :novel iteatures ed? the invention 'will be tally described in the sn'bjoined specification and particularly (pointed out in the following claims.

F'gu-ne 1 1s a side elevation and partial section of an oil-can emhodyin my invention, the spout and can rbody eing shown connected for use, the lbeing-taiken on the line 1-;1, Fig. 3; Fig. 2 is a top plan view of [the can :body, showing-:the port -.or member of :the spout connection :which is formed integrally therewith; Fig. '8 is an inner end wew of :the spout'and the parts permanently :attached thereto, :including the member-of the connection which ieotipcrotes aznd interlocks with the member on the can bod-y; Fig. 4zis a side relevation-oftthe lower end of the spout and the attached member of the connection, :the mdg'aocnt cap and washer being shown in diam'etral section.

Referring to "the drawing, lthe :can body 1, of usual shape and :made of isheet mete'lstamped and spun up toshmpe, :lm-s .a'tits top an opening 2 which is surrounded by :a -ci cular bend or neck 8 dorrnedby turning up the metal and then ibendm g It :over inward,

see Fig. l, and the dinner 'wallLe f'the [head is shaped to present miturned cam 1 ortions. Herein tthese cam JOHlElOllS :are :e iown .as

=';p posite semi-circa ar spinal flanges 4,

point '6 of the opposite the high which in effect are interrupted screwthreads, the high point 5 of each flange being above and spaced apart from the low ange. In practice -i'nt ofeach flange is substantially flush wit 1 the top of the bead 3, and the inner wall of the bead increases gradually in depth to the low point of the flange, and consequently each flange gradually decreases in width from its big shown in Ei 2. The flanges constitute one part or mom 1' of the separable connection between the-cam body and thetaper-ing spent 7, which spout is in practice made oi sheetmetal, and provided near its lower end with an external annular enlargement -or rib '8, termed iby spinning or otherwise.

The base b which the spout is secured oil-tight to th s bodyv comprises a circular cap .9 having a depending peniphera'l lip 10, and :a smaller circular disk 11 having e depending annular lip 12, outturned to present opposite semi-circular spiral flanges 13. As shown in 'Eig. 4ltl16 lip '12 is of greatest depth at the low point 14 of each flange 13 and gradually decreases in depth to the high :point 1 5 of the :flmnge, the high point of one :fiange being above :and spaced apart from athe low :poi nbof 'the other flange. The spiral flanges 13 are of the same pitch as the flanges 4, with which they cooperate and interlock by relative rotative :movement of *the spout and can body, and the flanges 113 constitute the connecting member on the spent.

The cap-9 and disk 11 are centrally apertured to receive the lower end of the spout, the cap abutting against-the rib 8, while the disk 11 seats squarely and firmly upon the inner 'faec of the cap, leaving an annular spncebctween'the lips 10 and 12, in which is inserted aapacking ring or gasket 16. Both the cap and the dipped disk 11 are readily stampedor spun 'from sheet metal, and can be made zatn'small cost. The diameters-of the lips l0 and 12 aresuch that the exposed face odi'thegasket 16 will seat upon the head 3 when :the spout andcan body are connected see Fig. :1.

iin order to secure :the parts of the base rigidly together and to the spout the projecting end of the latter beyond the disk 11 is ltunned over or spun down upon the adjacent face of the dis 111,-at 1.7, Figs. 1 and 3, whereby .the disk is clamped securely against the cap '19,-'8;11d the 'latter is in turn 1120 its low point, as

held securely against the stop-rib '8- on the spout, without the use of solder or other means. a

To connect the spout and the can body the base of the spout is set upon the body so that the low points or endsl4 of the flanges 13 can press downward at the high points or ends 5 of the flanges 4, within the bead 3. In such position the flanges 13 are seated upon the upper faces of the flanges 4, and by relative movement of the spout and the body each of the flanges-13 is caused to pass under one of the flanges 4, the opposed and adjacent faces of the coiiperatingpairs of flanges actin to draw the spout toward the body, and t erebythe gasket 16 is compressed oil-tight upon-the bead 3. The role tative movement thus operates to screw the spout into oil-tight connection with the body, as will be obvious, the compressive action upon the gasket being determined by the relative angular movement described. In

order. to separate the spout from thecan body the reverse rotation first relieves the pressure on the gaskets and then brings the two sets of interlocked flanges into unlocked or disenga ed position, as will be obvious.

Preferab y the exterior of the lip 10 Will be milled or roughened, as is customary, to facilitate the attachment or removal of the spout.

Having fully described my. invention, what I claim as new and desire to secure by Letters Patent is:

1, The combination with a sheet-metal can body having an opening in its top and opposite, inturned and integral semi-circular,

spiral flanges around the openin of a spout having an attached disk provide with a depending annular lip, and into al, outturned semi-circular spiral flanges ormed on the lip, to pass under and interlock with the flanges on the can body and fliereby connect the spout and said body, the high point of each flange of a pair being directly above the'low point offthe other flange of the pair.

2. The combination with a sheet-metal can body having an opening in its top anda surrounding, continuous annular bead provided with integral inturned opposite and semicircular spiral flanges, of a spout having an attached cap and a disk, provided with depending concentric annular lips, a gasket interposed between the lips, to seat upon the bead, and lateral, semi-circular spiral flanges on the inner lip, to coiiperate and interlock with the flanges on the body and thereby compress the gasket upon the bead, the latter engaging the gasket between the outer lip,

and the peripheral edges of the flanges on the inner lip.

3. The combination with asheet-metal can body having an opening in its top and a surrounding, continuous annular bead having its inner wall inturned to form a plurality 0 symmetrical s iral flanges integral therew1th,of a spout aving attached to it a cap with 9. depending annular lip, a disk within the on and having 9. depending annular lip and interlocking with the flanges on the can body to' compress the gasket upon the bead and connect said body and spout fluid-tight. 4. The combination with a tapered spout having an annularly and peripherally lipped cap, of an annularly lipped disk centrally apertured for the spout and seated on the cap and within it, an interrupted and outturned external'spiral thread formed on the lip of thedisk, a can body having an opening in' its top and a continuous circular bead surrounding the opening, the inner wall of the bead having formed upon it an integral inturned interrupted spiral thread of the pitch of the thread on the lip, and a gasket held between the annular lips of the disk and cap, interlocking of the flanges by relative rotation of the sfiout and can body drawing the parts toget er and compressing the gasket upon the bead and between it and the cap, to form an oil-tight joint.

5. Thecombination with a sheet-metal can body having an opening in its top and a surrounding continuous' and annular head the inner wall of which is provided with a plurality of inturned symmetrical spiral flanges, of a spout having an attached disk provided with a like number of outturned and symmetrical flanges ada ted to pass under and interlock with the anges on the can body by relative rotation of said spout and body, thereby to draw the disk and bead toward each other, the .high point of each spiral flange being adjacent the low point of another spiral flange of the same set.

6. The combination with a sheet-metal can body having an opening in its top and a surrounding continuousand annular bead the inner wall of which presents a plurality of inturned symmetrical s iral flanges, of a spout having an attached disk to extend over the bead and provided .with a plurality of out-turned and symmetrical spiral flanges of substantially the same length as the spiral flange of the body adapted to enter the opening in the can body by relative rotation of the latter and the spout, to thereby draw the disk and head toward each other.
